64 Safety and Security
Occupant safety
Warning!G
The service life of the passenger front airbag
extends to the date indicated on the label lo-
cated on the driver side B pillar. To provide
continued reliability after that date, they
should be inspected by an authorized
Mercedes-Benz Light Truck Center at that
time and replaced when necessary.
Warning!G
To reduce the risk of injury when the front
airbags inflate, it is very important for the
driver and front passenger to always be in a
properly seated position and to wear your
seat belt.
For maximum protection in the event of a
collision always be in normal seated position
with your back against the backrest. Fasten
your seat belt and make sure it is properly
positioned on your body (
page 68).
Since the airbag inflates with considerable
speed and force, a proper seating and hands
on steering wheel position will help to keep
you at a safe distance from the airbag.
Occupants who are unbelted, out of position
or too close to the airbag can be seriously
injured or killed by an airbag as it inflates
with great force in the blink of an eye:
Sit properly belted in a nearly upright
position with your back against the
backrest.
Adjust the driver seat as far as possible
rearward, still permitting proper opera-
tion of vehicle controls. The distance
from the center of the driver’s breast-
bone to the center of the airbag cover on
the steering wheel must be at least
ten inches (25 cm) or more. You should
be able to accomplish this by a combina-
tion of adjustments to the seat and
steering wheel. If you have any prob-
lems, please see an authorized
Mercedes-Benz Light Truck Center.
Do not lean with your head or chest
close to the steering wheel or dash-
board.
Keep hands on the outside of steering
wheel rim. Placing hands and arms in-
side the rim can increase the risk and
potential severity of hand/arm injury
when driver front airbag inflates.
Adjust the front passenger seat as far as
possible rearward from the dashboard
when the seat is occupied.

For more information on seat adjustment,
see the “Getting started” section
(

Easy-entry/exit feature
This feature allows for easier entry into and
exit from the vehicle.
The easy-entry/exit feature can be
switched on or off, see “Activating
easy-entry/exit feature” (
page 143).
When the SmartKey is inserted in the start-
er switch and the driver’s door is closed,
the steering wheel returns to the last set
position.When exiting the vehicle with the
easy-entry/exit feature activated, the
steering wheel tilts upwards when you
remove the SmartKey from the starter
switch,
or
open the driver’s door with the
SmartKey in starter switch
position0or1.
Warning!G
You must make sure no one can become
trapped or injured by the moving steering
wheel when the easy-entry/exit feature is
activated.
To stop steering wheel movement, do one of
the following
Move steering column lever
(
page 40).
Press memory position switch
(
page 108).
Do not leave children unattended in the ve-
hicle, or with access to an unlocked vehicle.
Children could open the driver’s door an un-
intentionally activate the easy-entry/exit
feature, which could result in an accident
and/or serious personal injury.
i
If the current position for the steering
wheel is in the uppermost tilt position,
the steering wheel will no longer be
able to move upward when the
easy-entry/exit feature is activated.

Seats
Installing front seat head restraint
Press switch1 upwards and hold for
about five seconds.
Press the head restraint down until it
engages.
Adjust head restraint to the desired
position.Synchronizing head restraints and seat
adjustment fore and aft for front seats
If the power supply was interrupted (bat-
tery disconnected or discharged), the head
restraints and the seat adjustment fore
and aft are no longer adjusted
automatically.
The head restraints and the seat adjust-
ment fore and aft must be resynchronized:
Switch on the ignition (page 35).
Move the seat completely forward
(
page 38) and the head restraint fully
down (
page 39) and hold the switch-
es for approximately one second.
Rear seat head restraints
Warning!G
For your protection, drive only with properly
positioned head restraints.
Adjust head restraint so that the center of
the head restraint supports the back of the
head at eye level. This will reduce the poten-
tial for injury to the head and neck in the
event of an accident or similar situation.
Do not drive the vehicle without the seat
head restraints. Head restraints are intend-
ed to help reduce injuries during an acci-
dent.
